LAMP-CHIMNEY RAISER.

SPECIFiCA'IION forming part of Letters Patent No. 477,930, dated (Tune28, 1892.

Application filed September 24,1891- Serial No. 406,634- (No model.)

To all whom it may concern.-

Be it known that I, EDWIN M. GOLDSMITH, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Lamp-Ohimney Raisers,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention consists in providing the chimney of a lamp with means,substantially as hereinafter described, for mechanically raising thesame, so that access may be had to the burner or for other purposeswithout direct engagement or contact of the hand with the chimney.

Figure 1 represents a perspective View of a lamp-chimney raiserembodying my inven tion. Fig. 2 represents a side elevation thereof.

Similar letters of reference indicate corresponding parts in the twofigures.

Referring to the drawings, A designates the burner portion of a lamp ofanydesired construction.

B designates a rising-and-falling plate of annular form, the samesupporting the lampchimney and provided with elastic fingers O forfirmly retaining said chimneyin position. On said plate B are verticallyarranged sleeves D, through which are freely passed the rods E, thelatter being secured to a collar F, which is fixed in any suitablemanner to a proper portion of the lamp below the burner. To said collaror portion is attached an ear G, 011 which is mounted a bifurcated leverH, the latter having a thumb or finger portion J and a limb K, thelatter being formed with upturned lips L at its ends to preventdisengagement of the lever from the plate when the latter is raised.Projecting horizontally from the plate B are pins M, the same beingabove the limb K of the lever and so disposed in relation thereto thatwhen the lever is operated said limb rides against said pins M, wherebythe plate B and parts carried by the same are elevated.

The operation is as follows, the parts being shown in normal position inFig. 1: When it is desired to raise the chimney in order to light thelamp or for other purposes, the portion J of the lever is depressed,whereby the limb K thereof rises, and as the latter bears upwardlyagainst the pins M the plate 13, and consequently the 1amp-chi1nney, areelevated, whereby the burner is accessible. A match or other lightingmedium may now be applied to the burner below the bottom of the chimney,the efiect of which is evident. It is evident that when pressure isreleased from the portion J of the lever the limb K lowers, and with itthe lamp-chimney. The rising motion of the chimney is limited by thelips L, which engage with the pins M, and also prevent said pins frompassing under the lever. The motions of the plate Bare guided bythe'sleeves D and rods E, so that the chimney is steadied and preventedfrom overturning.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a lamp chimney raiser, the combination of a plate forsupportingachimney,having sleeves thereon and pins projecting from theedge thereof, rods supported by the lampneck and freely passing throughsaid sleeves, and-a bifurcated lever pivotally connected to thelamp-neck and adapted to bear-against the pins on said plate to raisethe chimney and plate, said lever having lips at its ends to prevent;disengagement of said lever from the plate when the latter is raised,substantially as described.
